There is increasing evidence that early mammals evolved rapidly into a range of body forms and habitats, right under the noses of the dinosaurs.

Temporal niche expansion in mammals from a nocturnal ancestor after dinosaur extinction
TLDR
Phylogenetic analysis of behavioural data across all living mammalian orders suggests the earliest mammals were nocturnal, and other modes such as cathemerality and strict diurnality did not arise until the end of the Cretaceous and early Cenozoic.
Temporal niche expansion in mammals from a nocturnal ancestor after dinosaur extinction
TLDR
An extensive behavioural dataset for 2415 species from all extant orders is used to reconstruct ancestral activity patterns across Mammalia and finds strong support for the nocturnal origin of mammals and the Cenozoic appearance of diurnality, although cathemerality may have appeared in the late Cretaceous.
The smallest eating the largest: the oldest mammalian feeding traces on dinosaur bone from the Late Jurassic of the Junggar Basin (northwestern China)
TLDR
The traces represent the oldest direct evidence for mammalian feeding behaviour in the fossil record and expand the known range of the early mammalian feeding repertoire significantly and shed light on the palaeobiology and palaeoecology of early mammals, a field that has remained evasive for a long time.

Pallial patterning and the origin of the isocortex
TLDR
A developmental hypothesis is advanced in which the mechanisms of evolutionary brain growth remain partly conserved across amniotes (mammals, reptiles and birds), all based on Pax6 signaling or related morphogens.
The evolution of protein domain repertoires: shedding light on the origins of herpesviruses
TLDR
Differences in domain composition may not just explain HV host range and tissue tropism, but also provide hints to the origins of herpesviruses.
The evolution of protein domain repertoires: Shedding light on the origins of the Herpesviridae family
TLDR
Differences in domain composition may not only explain HV host range and tissue tropism, but also provide hints to the origins of HVs.
Role of Two-Pore Channels in Embryonic Development and Cellular Differentiation.
TLDR
The role of NAADP/TPC/Ca2+ signaling during early embryonic development and cellular differentiation is reviewed, with particular attention to the role of TPC2 in the development and maturation of early neuromuscular activity in zebrafish and during the differentiation of isolated osteoclasts, endothelial cells, and keratinocytes.
Stromal-Epithelial Interactions during Mammary Gland Development
TLDR
This chapter summarizes the current knowledge about the complex nature of interactions between the mammary epithelium and stroma during mammary gland development in different mammalian species.
Newly characterized bovine mammary stromal region with epithelial properties supports representative epithelial outgrowth development from transplanted stem cells
TLDR
Gene markers and activators of the mesenchymal-to-epithelial transition were highly enriched in the epithelial gene cluster and may contribute to the acquired epithelial properties of this stromal layer.

Rates of Dinosaur Body Mass Evolution Indicate 170 Million Years of Sustained Ecological Innovation on the Avian Stem Lineage
Early dinosaurs showed rapid evolutionary rates, which were sustained on the line leading to birds. Maintenance of evolvability in key lineages might explain the uneven distribution of trait…
Mammals from the Age of Dinosaurs: Origins, Evolution, and Structure
TLDR
The Mesozoic Mammals in Space and Time and the Interrelationships of Mesozoics Mammals are studied to understand the distribution and relationships of these animals.
Transformation and diversification in early mammal evolution
TLDR
Newly discovered fossils show that evolution of such key characters as the middle ear and the tribosphenic teeth is far more labile among Mesozoic mammals.
Evidence for a Mid-Jurassic Adaptive Radiation in Mammals
TLDR
It is demonstrated that sustained morphological innovation in Triassic stem-group mammals culminated in a global adaptive radiation of crown-group members during the Early to Middle Jurassic, supporting the "long-fuse" model of diversification in Mesozoic therians.
Mesozoic mammals of China: implications for phylogeny and early evolution of mammals
TLDR
The superb specimens from nearly all major groups of Mesozoic mammals in China provided a great amount of information that contributed to understanding on some major issues in phylogeny and the early evolution of mammals, such as divergences of mammals and the evolution of the mammalian middle ear.
A Jurassic mammaliaform and the earliest mammalian evolutionary adaptations
TLDR
A new fossil from the Middle Jurassic that has a mandibular middle ear, a gradational transition of thoracolumbar vertebrae and primitive ankle features, but highly derived molars with a high crown and multiple roots that are partially fused is described.
Adaptive radiation of multituberculate mammals before the extinction of dinosaurs
TLDR
It is shown that in arguably the most evolutionarily successful clade of Mesozoic mammals, the Multituberculata, an adaptive radiation began at least 20 million years before the extinction of non-avian dinosaurs and continued across the Cretaceous–Paleogene boundary.
Dietary specializations and diversity in feeding ecology of the earliest stem mammals
TLDR
An integrated analysis using synchrotron X-ray tomography and analyses of biomechanics, finite element models and tooth microwear textures reveals previously hidden trophic specialization at the base of the mammalian radiation; hence even the earliest mammaliaforms were beginning to diversify—morphologically, functionally and ecologically.
Impacts of the Cretaceous Terrestrial Revolution and KPg Extinction on Mammal Diversification
TLDR
Molecular phylogenetic analysis, calibrated with fossils, resolves the time frame of the mammalian radiation and diversification analyses suggest important roles for the Cretaceous Terrestrial Revolution and KPg mass extinction in opening up ecospace that promoted interordinal and intraordinal diversification, respectively.
Postcranial Skeleton of the Cretaceous Mammal Akidolestes cifellii and Its Locomotor Adaptations
TLDR
The postcranial skeleton of Akidolestes cifellii, a spalacotheroid species from the Lower Cretaceous Yixian Formation of northeastern China is described and suggests that a greater ecomorphological differentiation occurred in these stem therian mammals than previously thought and that ecological differentiation is a major pattern in early therian mammal evolution.
